摘要
基于结构力学及随机过程理论 ,分析桥梁所承受的车辆冲击力与车辆、桥梁的动力特性及桥面平整度之间的关系 ,提出了确定冲击系数的一种新方法。
Based on the theories of structural mechanics and random process, the relations among the impacting coefficient, the dynamical property of vehicle and bridge and the plainness of bridge surface are analyzed. A new method is put forward for calculating the impacting coefficient. The simularities and differences between the bridge design codes and the method in this paper are discussed.
